Interesting. What is happening is that tt_params ends up storing its
parameters in $self->{__TT_PARAMS}, so if you call $self->tt_params( c
=> $self ), then you end up with $self->{__TT_PARAMS}->{c} = $self.
Hence your circular reference.
You can avoid the problem by using tt_pre_process (like in my example)
instead of tt_params. The end result would be the same.
Maybe I'll add a notice in the docs for CGI::Application::Plugin::TT
to warn about that.
Cheers,
